BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when an operator manually mounts an electronic component such as an IC, a transistor, a capacitor, or a resistor on a printed wiring board, determines the mounting position of the component on the printed wiring board. The present invention relates to a component mounting work auxiliary device that facilitates the mounting work of a worker by sequentially instructing the component mounting work auxiliary device. In particular, the present invention relates to a device that allows an operator to efficiently mount a component on a printed wiring board by using it in combination with a light spot type component mounting position indicating device. Further, the present invention relates to a component mounting work assisting device suitable not only for mounting components on a printed wiring board but also for assisting mounting or assembling components of other types.

2. Description of the Related Art When mounting electronic parts such as ICs, transistors, capacitors, and resistors on a printed wiring board, the parts are automatically mounted on a large quantity of printed wiring boards. There is an automatic component mounting device. On the other hand, if the above-mentioned automatic component mounting device is used, when mounting components on a large number of different types of printed wiring boards, the efficiency will be extremely poor. It is generally done by. In mounting components on such a small amount and various types of printed wiring boards, it is often the case that a worker alone mounts all components using a component mounting position indicating device. As a conventionally known component mounting position indicating device, an optical indicator for indicating a position where each electronic component such as an IC is to be mounted on a printed wiring board by spot light, and a mounting procedure of each component are stored in advance. Some include a memory and a controller that controls the light indicator based on a mounting procedure of the memory. When an electronic component is mounted on a printed wiring board using such a component mounting position indicator, the controller controls the optical indicator in accordance with the component mounting procedure registered in the memory in advance, so that the printed wiring can be spotted. The component mounting positions on the board are sequentially indicated.
In addition, the electronic component to be mounted among the electronic components previously arranged in the component box is supplied to the worker simultaneously with the instruction of the mounting position by the spot light by the component supply device. The operator can mount each electronic component appropriately at the component mounting position on the printed wiring board by simply mounting the supplied electronic component at the position on the printed wiring board designated by the spot light. it can. When using such a component mounting position indicating device, information necessary for mounting, for example, component information indicating the standard of electronic components, circuit symbol of each electronic component to be mounted, number of electronic components to be mounted, each electronic component is stored. Information such as precautions for mounting the parts box and electronic parts on the printed wiring board is displayed in characters on the display device such as a liquid crystal screen mounted on the front of the operator or at a position easy to see, and the operator can The electronic component mounting work is carried out while checking these characters. By using such a component mounting position indicating device, the mounting work of the component can be facilitated, so that even an unskilled person can perform the mounting work, and the mounting of misplaced electronic components and the wrong mounting position, etc. Since the occurrence of mistakes is reduced, it is possible to create a high quality printed circuit board on which components are mounted.

[0003]

By the way, in the conventional component mounting position indicating device, the information displayed on the display device is only information in characters. Therefore, the operator can check the already mounted parts and the parts to be mounted, check the consistency between the arranged parts and the part information and circuit symbols displayed on the display device, or the worker can check the printed wiring board. However, there is a problem in that it is very difficult to check the consistency between the mounting method of the mounted component, the mounting method displayed on the display device, and the precautions for mounting.

Further, when the conventional component mounting position pointing device as described above is used, all types of components to be mounted on the printed wiring board are arranged so that they are housed in advance at predetermined positions in the component box. I have to keep it. However, there are many types of printed wiring boards on which components should be mounted,
Moreover, for small lots, the serving operation must be performed frequently, which requires time and labor to prepare the serving, and further increases the possibility of serving mistakes. For this reason, the conventional component mounting position indicating device has a problem that it is rarely used in such a case because the efficiency is deteriorated rather than improved in the production of a large number of kinds of printed wiring boards.

Further, when a complicated mounting work must be performed when mounting a component on a printed wiring board, the worker can perform a complicated mounting work in addition to the predetermined information displayed on the display device. It is common to carry out the mounting work with reference to a detailed description of a work instruction. However, since the work instructions that have been used in the past are created with a description that is very difficult for a worker who is inexperienced to implement, it is necessary to let an inexperienced worker perform efficient implementation work. Was very difficult. In addition, if there are many types of printed wiring boards on which components should be mounted and that the number of printed wiring boards is small, it is necessary to create a work instruction sheet for each printed wiring board. There is also a problem that it takes a lot of time and cost to create it. In particular, for a product of a large variety and a small lot production type, the production of such a work instruction sheet, which causes a high cost, is a heavy burden, and improvement is desired.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a component mounting work assisting device in which a worker can easily perform a mounting work. In addition, by designating an appropriate component type so that only the mounting instruction of the component is given, it is possible to easily perform the mounting work without arranging a plurality of types of components in advance. An object is to provide a component mounting work auxiliary device. Further, another object of the present invention is to provide a component mounting work assisting device in which work instruction data that provides easy-to-understand work instructions to a worker can be easily created on the individual user side.

The components are mounted on the printed wiring board installed on the light indicating device 7A while checking the spot light emitted to the printed wiring board installed on the device 7A. FIG. 2 shows an example of a screen display displayed on the display 5A during the component mounting work. FIG. 2 is a conceptual diagram showing an example of a mounting work instruction screen during component mounting. The mounting work instruction screen shown in this embodiment can be roughly divided into three display contents of the data display portion A, the board image entire display portion B, and the board image enlarged display portion C. Will be described below.

First, the data display section A will be briefly described. The data display section A displays work information. The work information is included in the part data (predetermined introduction information about the part). In this embodiment, as work information, "circuit symbol", "part name", "number of parts", "polarity"
The example in which each information such as is displayed is shown. The circuit symbol (C7 in the figure) is a circuit symbol attached to the component currently mounted. For example, it shows the position on the board where the component is to be placed. The component name is the general name given to the component currently being mounted and the electrical characteristics (that is, the standard) of the component (for example, tantalum capacitor 0.1 μ · 50 V or carbon film resistor 2.2 kΩ · 1 / 8W etc.). The number of components indicates the total number of components currently mounted on the printed wiring board on which the mounting work is performed, and the number of components designated at the current mounting position. In addition, in this embodiment, since the example in which the "tantalum capacitor" is displayed as the component to be mounted is shown, the polarity is also displayed. In other words, the capacitors have polarities, and if the capacitors are mounted on the printed wiring board with the polarities reversed, the circuit on the board will not operate normally. Display a message that calls attention to the action. As an example of the method of displaying the polarity, among the four directions of arrows corresponding to up, down, left, and right, an arrow indicating the direction in which a terminal of a predetermined polarity (for example, +) should be located when mounting the currently designated component is used. There is a method of displaying the light. When pointing the insertion position of a component having polarity, at the same time, change the background color of the screen to a predetermined color (for example, red) that calls attention, or blink the predetermined color to check the polarity. The worker may be strongly informed of what should be done.

The rectangles shown in association with each display item (that is, circuit symbol, component name, number of components, polarity) indicate check boxes, and each time the check box is clicked using a mouse or the like. In addition, a check mark is displayed on the check box. This check box is for deciding whether or not to use the voice guidance. When the check mark is put in the check box (or when the check mark is removed), the voice guidance is provided at the time of mounting. . That is, the corresponding display item is read aloud during the mounting work. This embodiment shows an example in which the check mark of the circuit symbol and the check mark of the polarity in the uppermost stage are included, and in that case, the circuit symbol "C7" is read aloud and then " The voice is emitted as "Polarity is up". If the operator can appropriately select and use such voice guidance, the operator can confirm the correctness of the parts picked up for mounting without actually looking at the display screen of the display 5A. Therefore, the mounting work can be performed quickly and the mounting efficiency is improved, which is very preferable. For example, the operator can quickly check the circuit symbol on the board by listening to the voice of the circuit symbol "C7" without looking at the screen. Although not shown in this embodiment, in addition to the above, in the data display section A, for example, the tray number of the component box storing the component to be mounted at the mounting position and the current mounting work in the mounting process. The number of steps, etc. may be displayed on the data display section A.

Next, the board image whole display portion B will be briefly described. The entire board image display section B displays a board graphics image of the entire printed wiring board on which the mounting work is performed (the graphics image may be an illustration image or a photo image). The graphics image displayed on the board image whole display portion B is a board image in which components are already mounted when a predetermined mounting process is completed. A board image in which components are mounted in each predetermined mounting process (actual photograph is easy to use, but may be an illustration) may be captured via, for example, the image input unit 6A, and then stored in a hard disk (external storage device 8A). ) Or RAM 3 or the like. You may use what was extracted from the video image (moving image) so that it may mention later. Also,
The board image with parts mounted in each predetermined mounting process is
A storage medium, which is included in the work procedure data created by another device without being created by this device and stores the created work procedure data, is set in this device as the external storage device 8A. You may be allowed to do so. The board image displayed on the board image whole display portion B is a component of the printed wiring board which is a component mounting target in the work step selected from a plurality of board images corresponding to the currently performed work step. It is a mounted graphics image (that is, mounting board image data). However, for convenience, in the drawing, only some of the components (for example, IC) mounted on the printed wiring board are illustrated, and other components (for example, capacitors and resistors) are not shown. In the actual display, finer parts are also displayed (for example, in a photographed image) mounted on the printed wiring board. In the entire board image display section B, the entire image of the printed wiring board that is the mounting work target is displayed as the board image, and the current mounting work point (that is, mounting position) of the component that is the mounting target is indicated by a dotted line. It is represented by the intersection of the vertical and horizontal lines shown. The vertical line display and the horizontal line display sequentially move on the board image as the component mounting process progresses. By the intersection of these vertical and horizontal lines,
The operator can confirm the mounting position from the viewpoint of the entire printed wiring board.

Next, the board image enlarged display portion C will be briefly described. In the board image enlarged display portion C, when the mounting position label is selected as shown in the figure, a graphics image of the printed wiring board in which a part of the entire printed wiring board on which the mounting work is performed is enlarged is displayed. To be done. On the other hand, when the component label is selected, the graphics image (that is, component image data) of the designated individual component is displayed. In the mounting position label selected state, the graphic image of the printed wiring board displayed in the board image enlarged display portion C is the same as that displayed in the board image whole display portion B. Component mounting is completed when a predetermined mounting process is completed. Board image (that is, mounting board image data), and an image image (a photographic image or a CG illustration image may be displayed) in which a partial range of the board image is enlarged and displayed.
Is. The display of the graphics image in the board image enlargement display portion C is a window display, and an enlarged partial range of the board image is displayed in the window display. Scroll bars SB are displayed on the left and right of the window, and the operator operates the scroll bar SB up, down, left, and right with a mouse or the like to display the graphics image displayed on the window on another printed wiring board. The image can be appropriately changed to a partially enlarged image. A label Cd for switching display between "mounting position" and "component" is displayed in the window display, and the operator clicks the label Cd display with a mouse or the like to display the enlarged image image of the board. It is possible to switch the display between the component image and the component image. This component image is a graphic image of individual components.If the component currently being mounted is a tantalum capacitor, an enlarged image of only the tantalum capacitor is displayed.If it is a carbon film resistor, only the carbon film resistor is enlarged. Display the image you made. At this time, the previously registered color code may be displayed. By referring to the component image displayed in this manner, the operator can confirm the component to be mounted without error by referring to the image image. The data format of the graphics image may be any type such as jpg or BMP.

A large number of components mounted on the printed wiring board are displayed on the enlarged board image displayed in the window. At the time of mounting work, the mounting work point (that is, the mounting position) of the component currently targeted for component mounting work
Is a circle Ca colored with a predetermined color (for example, red)
(In FIG. 2, for convenience of illustration, the color of the circle Ca is shown in halftone). That is, the part indicated by the red circle Ca is the current mounting work target part. In addition, a component which is considered to have already been mounted in the mounting process (that is, a component whose mounting work point has already been designated) is additionally displayed with a dot display object colored in a predetermined color (for example, blue). (However, in FIG. 2, an asterisk is attached for convenience of illustration). That is, the parts indicated by blue dots are the parts for which mounting work has been completed. Further, the parts which are considered not to be mounted yet in the mounting process (that is, the parts for which the mounting work point has not been specified yet) are displayed by adding a point display object colored in a predetermined color (for example, yellow). (However, in FIG. 2, for the sake of illustration, it is shown with a filled circle). That is,
The parts indicated by yellow dots are the parts to be mounted. In this way, by displaying the mounted components and the unmounted components in different modes, it is possible to easily distinguish them. The different display modes are not limited to different colors, and any other method may be used. In the light pointing device 7A, as is known, the irradiation position of the light spot is switched according to the pedal operation or the like according to the progress of the actual component insertion work on the board. Synchronously, the above-described position display and the like in the present embodiment are performed. A specific description of various display controls in the enlarged image of the board during the mounting work will be described later.

It should be noted that the display positions of the graphics image of the entire printed wiring board on which the mounting work described above and the graphics image of the printed wiring board on which a part of the entire printed wiring board on which the mounting work is performed are enlarged are appropriately performed. You may be able to display by replacing with. That is, the graphics image of the entire printed wiring board is displayed large on the right side of the screen shown in FIG. 2, and the graphics image of the printed wiring board in which a part of the entire printed wiring board is enlarged is displayed on the screen shown in FIG. It may be displayed in the lower left.

The component mounting work auxiliary device according to the present invention is
In addition to instructing the mounting position on the display 5A, the light instructing device 7A is controlled to sequentially illuminate the actual component mounting positions on the printed wiring board with spotlights, thereby instructing the operator of the component mounting positions. Therefore, the component mounting position instructing process for instructing the mounting position of the component will be described with reference to FIG. FIG. 3 is a flowchart showing an example of the component mounting position instruction processing. First, in step S1, user input is performed. This user input includes input of a board number for selecting a printed wiring board on which mounting work is to be performed, input of a process number for determining the order of performing mounting work, and the like, for example, in response to an operation of the operator 4A by the user. Is done. Furthermore, at the time of the user input, the user may directly input the component code of an appropriate component for which the mounting work is desired. For the explanation when inputting the part code directly,
It will be described later.

In step S2, various data necessary for the corresponding mounting work are read from the ROM 2 and the external storage device 8A according to the user input. For example, graphics image data of a printed wiring board or a component to be mounted, component data related to all components to be mounted on the substrate, process order data defining a mounting sequence of the component on the substrate, or step S9 described later. Read the installed data that is updated in. In this embodiment, the process sequence data includes at least a component code and one to a plurality of mounting position coordinates corresponding to the component code, and the component mounting position instructions are sequentially performed according to the process sequence data. The graphics image data of the substrate or the like may be created by an external personal computer, stored in the external storage device 8A, and read. Alternatively, graphics image data created by CAD may be used, and the CAD data may be appropriately converted so that it can be used in the present system, and the data may be read. In step S3, a predetermined screen is displayed on the display 5A. That is, a screen to be displayed on the board image whole display portion B or the board image enlarged display portion C in FIG. 2 described above is generated and displayed on the display 5A.

In step S4, it is determined whether or not the mounting work is started. For example, whether or not a mounting work start instruction is issued is determined by whether or not the user has clicked a predetermined switch such as "start mounting" displayed on the display 5A using a mouse or the like. When it is determined that the mounting work is started (YES in step S4), the component data and the mounting position data of the component to be mounted according to the process order data, the graphics image data of the component to be mounted, or updated in step S9 described later. The mounted data and the like are acquired (step S5), and screen control is performed on the display 5A so as to display the screen indicating the mounting position based on the acquired data (step S6). The screen control here mainly controls the display of the mounting position, the display of the mounted part, and the display of the non-mounted part. That is, in the board image enlarged display portion C in FIG. 2 described above, the mounting work point (that is, the mounting position) of the component targeted for the component mounting work is indicated by a circle colored in a predetermined color (for example, red). (Circle Ca in Figure 2
reference). Further, if there is mounted data at the end of the previous mounting work (see step S9 to be described later), the mounted component is given a predetermined color (for example, blue) based on the data.
Display with dots colored in (see the star in Fig. 2). Further, based on the data, the unmounted components are displayed with dots colored with a predetermined color (for example, yellow) (see the filled circle in FIG. 2).

In step S7, the light indicating device 7A is controlled based on the acquired data. That is, the light indicating device 7A
The components to be mounted are supplied to the worker from the component supply device (not shown) provided in the above, and the mounting position on the printed wiring board is irradiated with spot light. Step S
At 8, it is determined whether or not a foot switch (not shown) included in the light indicating device 7A has been operated by the light indicating device 7A. The foot switch is a switch used to sequentially move the spot light to the mounting position in the light indicating device 7A, and moves the mounting position one by one for each operation. Further, when the operation time of one time is a predetermined time or more, it is possible to return to the mounting position one before. When the foot switch is operated (Y in step S7)
S), the mounted data is updated (step S9), and it is determined whether or not the mounting work is ended (step S1).
0). The mounted data is data that records all the process sequence data that has already been mounted (or only the process sequence data that has finished mounting at the end) of the process sequence data. The mounting operation is restarted from the process sequence data recorded in the mounted data after the process sequence. When the mounting work is finished (that is, when the mounting work according to the process sequence data is all finished, or when the mounting work is temporarily stopped) (Y in step S10)
ES), and the process ends. If the mounting work is not completed (NO in step S10), the process returns to step S5, and the above-described processes are performed on the mounting position where the component is to be mounted next. That is, the processes of steps S5 to S10 are repeated.

In the above-described embodiment, a case has been described in which the mounting positions of all components including different types are sequentially designated according to the process sequence data corresponding to the process number input by the worker, but the present invention is not limited to this. In accordance with the designation of the specific type of component by the operator, only the mounting positions of the specific type of component can be collectively designated. For example, a worker attaches a part to be mounted in advance before carrying out the mounting work to a vinyl bag (hereinafter, referred to as a part bag) or the like with a label indicating a part code or a circuit symbol attached to the part. It suffices to store each in the inside and store a plurality of component bags in which components are classified according to each type in one predetermined component box. At the time of component mounting work, the worker takes out an arbitrary component bag from the component box and inputs the component code using the operator 4A or the like according to the label attached to the component bag. Then, the component mounting work assisting device described above displays the mounting position of the component corresponding to the input component code on the display 5A according to the component type indicated by the input component code and in a predetermined mounting order. The mounting position is designated by the spot light of the light indicating device 7A. Then, the operator takes out the component from the component bag and mounts the component at the designated mounting position on the printed wiring board. After finishing the component mounting at the mounting position, the worker pushes the foot switch. Then, the component mounting work assisting device instructs the next mounting position at which the same type of component is to be mounted, according to the operation of the foot switch. By repeating this, the mounting positions of the components of the same type are sequentially instructed until another type of component code is input.

In this case, the instruction display of the mounting position of the component of the type is performed in a predetermined sequence. When one sequence is completed, an end display may be displayed to prompt the operator to input another type of component code. Alternatively, without being limited to this, when one sequence ends, the process may return to the beginning of the sequence to display an instruction of the mounting position of the component. In that case, the operator can recognize that the mounting work of the component of the type has been completed when the position of the component already mounted is instructed again. As described above, according to this embodiment, the mounting position of the same type of component is repeatedly instructed until another component code is newly input, so that the component mounting error, the mounting direction, and the like are simultaneously confirmed. You will also be able to do that. Further, if the components are mounted by such a method, the component supply device having the trays for the types of the component codes, which the light indicating device 7A has, becomes unnecessary (that is, the operator needs 1
Since it suffices to keep a parts bag accommodating the kinds of parts at hand), the time and manpower conventionally required for arranging the parts in the part supply device are eliminated. Further, since the component is directly taken out from the component bag and the mounting work is performed, there is an advantage that a mistake in the arrangement of the component is eliminated. Further, since the worker directly inputs the component code of the component bag, the worker can obtain the advantage that the mounting work can be performed while confirming the components.

Further, if the component code or the like of the label attached to the component bag is converted into a bar code, the worker can start the mounting work only by reading the bar code of the component bag with a bar code reader. It is possible to perform efficient mounting work by eliminating the troublesomeness of inputting a component code by a person and an input error. Of course, the component supply device and the component bag may be used together. That is,
Among the components to be mounted on the printed wiring board, the components commonly mounted on many different types of printed wiring boards should be stored in the component supply device, and the other components should be stored in the component bag. The number of parts bags can be reduced, and the time required for bagging parts and mistakes in bagging parts can be reduced.

Although the mounting board image data displayed on the display 5A is used only during the mounting work in the above-described embodiment, a screen displaying the mounting board image data as shown in FIG. 2 is displayed. You may make it possible to input mounting position data using it. That is, the operator simply clicks on a predetermined component or position of the board image displayed on the image enlarged display portion C on the display 5A using a mouse or the like, and the data regarding the position where the component is mounted (that is, the mounting position Data) may be input. By doing so, efficient data input can be easily performed. Further, by using the software according to the present invention, input data is created by another computer, and the created input data is transferred to a mounting work personal computer through a communication network or a portable medium such as an FD. You may do it.

Further, in the component mounting work assisting apparatus of the present invention having the above-mentioned structure, the worker is required to display the display 5
Operate 4 to display work procedure movie data on A
It is possible to give an appropriate instruction by using A or the like.
It is possible to perform component mounting work on the printed wiring board installed above. Display 5 in that case
FIG. 4 shows an example of screen display during the component mounting work displayed in A. FIG. 4 is a conceptual diagram showing an example of a screen display when a mounting work instruction screen and a work procedure movie data screen are displayed simultaneously during component mounting. That is, in this embodiment, the mounting work instruction screen Wa and the work procedure movie data screens Wb and Wc are simultaneously displayed. Of course, only the mounting work instruction screen Wa may be displayed alone (see FIG. 2 described above), or only the work procedure movie data screen Wb or Wc may be displayed alone.

In this embodiment, the mounting work instruction screen Wa is displayed on the left side of FIG. The detailed display content of the mounting work instruction screen Wa has already been described with reference to FIG. 2, and thus the description thereof is omitted here. On the other hand, the work procedure movie data screen Wb or Wc is displayed on the right side of FIG. On the work procedure movie data screen Wb or Wc, work procedure movie data generated by the video input unit 11A for each predetermined component mounting work is displayed according to the process order data or the operator's designation. That is, a moving image (that is, a movie) recording the mounting work of actually mounting the predetermined component on the printed wiring board installed on the light indicating device 7A is displayed on the upper side screen Wb.
In addition, a still image recording the mounting work of actually mounting the predetermined components on the printed wiring board installed on the light indicating device 7A is displayed on the lower screen Wc. However, either one of the moving image and the still image may be selectively displayed instead of displaying both. When displaying still images, a plurality of still images may be displayed simultaneously instead of displaying only one still image. That is,
The predetermined mounting work may be displayed in a state in which a plurality of still images are frame-fed. The still image displayed on the work procedure movie data screen Wc is an image obtained by capturing or extracting a part of the moving image displayed on the work procedure movie data screen Wb.

When the work procedure movie data screens Wb and Wc are displayed on the display 5A, various other information may be displayed. Therefore, in this embodiment, an example in which the elapsed time T and the process progress instruction buttons Da and Db are displayed on the display 5A is illustrated. This elapsed time T is a predetermined time (for example, a time set at the time of data input processing described later) that is set in advance together with the start of the mounting work (that is, the start of displaying the moving image or the still image by the work procedure movie data screen Wb or Wc). Is displayed and the countdown is displayed according to the progress of the mounting work. When the predetermined time has passed, the count-up display is performed in reverse.
For example, if the standard time required to perform the mounting work displayed on the work procedure movie data screens Wb and Wc is set as the predetermined time, the worker can display the elapsed time T as described above and display the standard time. It becomes possible to easily proceed with the mounting work while comparing the specific working time with the time taken to actually mount the component. The process progress instruction buttons Da and Db are used to return the mounting work process (for example, when "Return" is clicked with a mouse or the like), or to advance the mounting work process (for example, "Next" with a mouse or the like). Button when you click). According to the operation of the process progress instruction buttons Da and Db, the mounting work content (that is, work procedure movie data) displayed on the work procedure movie data screens Wb and Wc is changed.

As described above, when mounting the component on the printed wiring board, the actual mounting of the component can be displayed on the display 5A as a moving image or a still image to express the detailed portion of the mounting work. I made it possible. As a result, even an inexperienced worker can easily perform component mounting work simply by following the instructions displayed on the screen. The substrate can be efficiently produced. Further, since the work time required for the mounting work is measured and displayed as the elapsed time in accordance with the change of the mounting work contents of the work procedure movie data screens Wb and Wc, the progress status of the mounting work for each worker can be displayed. You will be able to easily grasp each.

Next, the process of generating the work procedure movie data for each mounting work displayed on the work procedure movie data screens Wb and Wc will be briefly described. FIG. 5 is a flowchart showing an embodiment of the work procedure data creation process for creating work procedure movie data. First, video input is performed (step S11). That is, moving image data (video data) photographed by the user himself using a digital video camera or the like for each mounting operation is taken into the device side and stored in the external storage device 8A or the like. When the user actually shoots the mounting work of mounting the parts, if you shoot the mounting work from different angles using multiple digital cameras, multiple more detailed work procedure data will be generated simultaneously in the subsequent processing. can do.

Next, image data is created and edited (step S12). That is, still image data for each predetermined work process is generated from the captured moving image data. That is,
Capturing (extracting) desired images from video data
To generate still image data. In this case, not only the still image but also desired partial moving image data may be captured (extracted). Further, the extracted still image data and / or moving image data is edited as necessary. The still image data and / or the moving image data extracted for each work process is stored in the external storage device 8A (hard disk) or the like. Further, the captured moving image data (video data) may be stored in the external storage device 8A (hard disk) or the like. At this time, a predetermined name is given to the still image data and / or the moving image data extracted for each work process and stored. The names to be given are given so that the order of steps can be understood. The moving image data stored in the external storage device 8A or the like is displayed on the work procedure movie data screen Wb, and the still image data is displayed on the work procedure movie data screen Wc. Of course, moving images and still images are displayed on separate screens Wb, W
You may display on a common screen instead of displaying on c.
For example, a moving image may be displayed at one time and a still image may be displayed at another time. The still image data extracted corresponding to the work process can be used as the board image data (data displayed on the screen Wa) regarding the work process after being appropriately edited. Further, a work instruction sheet (work manual) can be easily created by printing out and using still image data extracted corresponding to the work process.

In step S13, the above step S12 is performed.
Corresponding to the still image data and / or the moving image data extracted for each work process, the user inputs arbitrary work information (work comment information, parts introduction information, etc.), and the input work information is used for each work process. It corresponds and is memorized. The work information given here includes, for example, information on tools used at the time of mounting work, information on introduction of parts for mounting work, and information on tray numbers of parts supplying devices for distributing parts (when the parts supplying device is used. There is a standard time for the mounting work. Further, the data for instructing each component mounting position on the board image image regarding the work process is also input and stored. In addition, the data for instructing each component mounting position on the board image image regarding the work process is displayed on the screen W.
By clicking a predetermined mounting position on the board image image displayed in a with a mouse and storing the data of the clicked position, it is possible to easily generate without trouble. In that case, the mounting position data for display may be generated and stored in synchronization with the mounting position indicating sequence by the light spot in the light indicating device 7A. For example, the mounting position pointing sequence by the light spot in the light pointing device 7A is activated, the pointing position by the light spot is moved step by step by operating the foot switch, and the light spot pointing position at each time is viewed and displayed on the screen Wa. The corresponding position on the board image may be clicked with the mouse.

By combining the still image data and / or moving image data extracted for each work process with the input work information, mounting position data, etc., work procedure data can be easily created. By reproducing the created work procedure data in sequence, the instruction / display processing of each mounting position can be performed as described in the embodiments of FIGS. 2 and 3. Further, as described above, it is possible to easily create a work instruction sheet of printed-out paper. In this way, since the moving image data of the actual mounting of the parts is captured and the work procedure data and the work instruction sheet are generated based on the image data, the work instruction which is easy for the worker to understand It becomes possible to easily generate a calligraphy in a short time. INDUSTRIAL APPLICABILITY The present invention is not limited to the mounting position instructing device and / or method for an electronic component on a printed wiring board as shown in the above embodiments, but can be used as a work assisting device and / or method for instructing other work procedures. .
